Abstract: A method and apparatus for performing a wireless local area network (WLAN) termination (WT) release procedure in a wireless communication system is provided. For the eNodeB (eNB) initiated WT release procedure, the eNB transmits a WT Release Request message to a WT via a Xw interface. For the WT initiated WT release procedure, the eNB receives a WT Release Required message from a WT via a Xw interface, and transmits a WT Release Confirm message to the WT via the Xw interface. The WT is a logical node that terminates the Xw interface.

Abstract: A method and apparatus for enhancing a handover procedure for supporting conditional handover in a wireless communication system. A source base station (e.g. source gNB/eNB) receives a message informing that a wireless device is handed over from the source base station to a target base station (e.g. target gNB/eNB). The target base station is one of candidate target base stations in the conditional handover procedure. After receiving the message, the source base station transmits a sequence number (SN) status transfer message to the target base station.

Abstract: Provided are a method for transmitting, by a base station in a wireless communication system, a vehicle to everything (V2X) message, and an apparatus for supporting the same. The base station may receive broadcast area information indicative of areas to which the V2X message will be broadcast, from a multi-cell coordination entity (MCE), receive the V2X message from a terminal, and transmit the received V2X message to a neighboring base station. Provided are a method for transmitting, by a V2X server in a wireless communication system, a vehicle to everything (V2X) message, and an apparatus for supporting the same. The V2X server may receive the V2X message transmitted by a base station from a serving/packet-gateway (S/P-GW), determine a broadcast of the received V2X message, and transmit the V2X message to a base station that belongs to the same multimedia broadcast single frequency network (MBSFN) area as the base station.

Abstract: A method and apparatus for performing access control and/or membership verification for dual connectivity in a wireless communication system is provided. A first evolved NodeB (eNB) transmits a closed subscriber group (CSG) membership status of a user equipment (UE) to a second eNB, which is a home eNB (HeNB), and receives at least one of a CSG identifier (ID) or a cell access mode of the second eNB from the second eNB. A mobility management entity (MME) may verify the CSG membership status of the UE and transmit the verified CSG membership status of the UE to the first eNB. And then, the first eNB transmits the verified CSG membership status of the UE to the second eNB.
